ABSTRACT:
A brush support combination is provided for dynamo-electric machines in which brushes are continuously urged against a commutator or slip ring. Each brush is carried by a brush arm which is in turn supported on a lead terminal of the machine. The lead terminals may be supported on an open ended motor housing or on an end cap which closes the open ended housing. The brush arm is formed of electrically conductive, flat resilient stock which supports a brush at one end. The other end is formed into a bight, the free end of which projects outwardly. The bight extends through an opening in the lead terminal, entry to which may be achieved through a throat communicating with the opening. In use the bight resiliently engages the edges defining the opening to retain the brush arm and to provide electrical contact with the terminal.
